Catalytic solid supported on calcined hydrotalcite for olefinic polymerisation

摘要

Catalyst solid for olefin polymerization comprisingA) at least one calcined hydrotalcite andB) at least one organic transition metal compound,and also a catalyst system comprising the catalyst solid, the use of the catalyst solid for the polymerization or copolymerization of olefins and a process for preparing polyolefins by polymerization or copolymerization of olefins in the presence of the catalyst solid.
